编译的时候报了几个错

[hustnaive]

1、

/usr/bin/m4:config.m4:10: cannot open `php-ext-embed/php_ext_embed.m4': Not a di
rectory

2、

checking for sample support... yes, shared
checking with libelf path... yes, shared
checking whether php_ext_embed_dir is correct... configure: error: php_ext_embed
.h is not exist
make: *** [sample/Makefile] Error 1

3、

依次执行下面的命令解决：

假设代码放在/tmp/php-ext-embed目录下面

#调整一下m4文件中的一些问题
sed -i -e 's/PHP_EXT_EMBED_DIR\=php-ext-embed/PHP_EXT_EMBED_DIR\=\/tmp\/php-ext-embed/g' /tmp/php-ext-embed/php_ext_embed.m4
sed -i -e 's/m4_include(php-ext-embed\/php_ext_embed.m4)/m4_include(\/tmp\/php-ext-embed\/php_ext_embed.m4)/g' /tmp/php-ext-embed/sample/config.m4

#生成配置文件
cd /tmp/php-ext-embed/sample && phpize && ./configure

#替换makefile中生成的错误路径（目前还没找到原因）
sed -i -e 's/tmp\/php-ext-embed\/sample\/\/tmp\/php-ext-embed/tmp\/php-ext-embed/g' /tmp/php-ext-embed/sample/Makefile

初接触扩展开发，对phpize和Makefile不是很熟悉，不清楚是我自己编译过程的问题还是代码本身的问题。问题解决过程提供给作者参考一下，如果作者有更好的方案烦请告知。
